<P>PROBLEM TO BE SOLVED: To provide an alkaline primary battery using nickel oxyhydroxide that can secure safety and reliability at the over-discharge, while realizing large capacity and improvement in high load characteristics. <P>SOLUTION: The positive electrode molded body 2 of the alkaline primary battery contains in the positive mix cobalt and zinc, or, in addition, nickel oxyhydroxide that contains either one out of Al, Ca, Mg, Ti, Sc, Fe, Mn, Y, Yb, and Er, and its theoretical electric capacity ratio is 1.10 or less. Or, it contains in the positive mix further manganese dioxide as a positive active material, and when the filling quantity of nickel oxyhydroxide is called Wng and the filling quantity of manganese dioxide is called Wmg, the theoretical electric capacity ratio is made (1.10×Wn+1.25×Wm)/(Wn+Wm) or less. <P>COPYRIGHT: (C)2003,JPO |
